This fit can be a snap engagement. The projections 5i may extend over the entire width of the arm 5c, or may extend over only part of the arm 5c or a plurality of projections 5i may be provided for a single arm 5c.

  As a material of each part of the container 1, arbitrary things can be used and resin is especially suitable. For example, it is particularly preferable that the container body 2, the lid 3 and the holder 5 be polyethylene and the retainer 4 be polypropylene, but the invention is not limited thereto. Any of the container body 2, the lid 3, the retainer 4 and the holder 5 may be transparent or translucent.

  A method of refilling the bag 7 will be described using the container 1 of the first embodiment of the present invention configured as described above.

  First, as shown in FIG. 6, the opened bag 7 is set (or housed) in the holder 5. The bag 7 is held by the bag holding portion 5 b of the holder 5, and the bottom surface of the bag 7 contacts the top surface of the bottom piece 5 e of the holder 5. Thereby, an appropriate relative positional relationship in the height direction between the opening 7 c of the bag 7 and the holder 5 is established.

  Next, as shown in FIG. 7, the retainer 4 is set (stored) in the holder 5 while expanding the inward notch portion 7 d of the opening 7 c of the bag 7 outward toward the inner peripheral surface of the holder 5. Do. At this time, the user fits the retainer tab 4 b of the retainer 4 with the holder tab 5 g of the holder 5. The retainer 4 is held by the upper surface of the holder tab 5g. As a result, the opening 4 c of the bag 7 is held in the expanded state by the retainer 4, and at that time, the relative movement between the retainer 4 and the bag 7 in the height direction is restricted by the holder 5. An appropriate relative positional relationship between the opening 7c of the second embodiment and the retainer 4 is established.

  When the retainer 4 is set to the holder 5 in this manner, if it is before setting these into the container main body 2, the control openings 5 f and 5 f of the holder 5 can be used to It is possible to control the posture of the bag 7 in the holder 5 by the user accessing or touching the outside surface of the holder 5 with fingers from the outside of the holder 5. Therefore, part or all of the opening 7c of the bag 7 comes out from between the cylindrical portion 5a of the holder 5 and the funnel portion 4c of the retainer 4 or wrinkles between the cylindrical portion 5a and the funnel portion 4c. If an improper set condition such as clogging occurs, it can be easily viewed from the outside before setting the retainer 4 and the holder 5 in the container body 2, and if necessary After the engagement between the retainer tab 4b and the holder tab 5g is released to lift the retainer 4 from the holder 5 and the posture of the bag 7 is changed by direct access to the bag through the control opening 5f, the retainer 4 is set again Can be easily corrected.

  Next, as shown in FIG. 8, the holder 5 in which the retainer 4 is set is set in the container body 2. At this time, since the bag 7 is held by the holder 5, the holder 5 in which the retainer 4 is set is accommodated in the container main body 2 while maintaining an appropriate relative positional relationship between the opening 7 c of the bag 7 and the retainer 4. can do. Further, since the side surface of the bag 7 is held by the holding portion 5b of the holder 5, the bag 7 can be prevented from expanding due to its weight, making it difficult to insert the bag 7 easily. The fitting portion 4a of the retainer 4 fits into the engagement rim 2f of the container body 2, and the retainer tab 4b fits in the area between the two engagement rims 2f. Here, since the tips of the retainer tab 4 and the holder tab 5 protrude outward more than the outer edge of the opening of the container body 2 (the outer edge of the support rim 2 e), when setting the holder 5 in the container body 2 And interference with the container main body 2 of the finger holding the holder tab 5 is suppressed, and the operation | work which sets the retainer 4 and the holder 5 to the container main body 2 can be made easy.

  As described above, as shown in FIG. 9, the retainer 4 and the holder 5 are set in the container body 2. The user can close the lid 3 to cover the opening of the container body 2 and lock the lid 3 in the closed state by engaging the fixture 3 c with the locking piece 2 i of the container body 2. .

And a holder 5 having a bag holder 5b. As a result, in a state where the opened bag 7 is accommodated in the holder 5, the retainer 4 is held by the retainer holding portion (upper surface of the holder tab 5g) such that the opening 4c of the bag 7 is held in the expanded state by the retainer 4. Then, relative movement between the retainer 4 and the bag 7 in the height direction is restricted by the holder 5. For this reason, by carrying out the process of accommodating the opened bag 7 in the holder 5 and setting the retainer 4 outside the container main body 2, an appropriate relative positional relationship between the opening 7 c of the bag 7 and the retainer 4 Can be easily established, and can be accommodated in the container main body 2 while maintaining this appropriate relative positional relationship so as to prevent the contents 6 from leaking into the container main body 2 Can.

  Further, in the present embodiment, the holder 5 has at least one control opening 5 f in at least one of the side surface and the bottom surface, and the user uses the control opening 5 f on the outer surface of the bag 7 housed in the holder 5. The posture of the bag 7 can be controlled by coming into contact with the outside of the holder 5. Therefore, when the process of housing the opened bag 7 in the holder 5 and setting the retainer 4 is performed outside the container body 2, an appropriate relative positional relationship between the opening 7 c of the bag 7 and the retainer 4 Establishment and re-establishment can be further facilitated.

  Further, in the present embodiment, at least one control opening 5 f extends from the side surface to the bottom surface of the holder 5. Therefore, the change in the horizontal direction and the change in the vertical direction of the posture of the bag 7 can be facilitated.

  Further, in the present embodiment, in a state where the opened bag 7 is accommodated in the holder 5, the retainer 4 is held by the retainer holding portion (holder tab 5g so that the opening 4c of the bag 7 is held in the expanded state by the retainer 4. When held on the upper surface, movement (in particular, horizontal movement) of at least a part of the opening 7 c of the bag 7 is restricted by the outer surface of the retainer 4 and the inner surface of the holder 5. As a result, the occurrence of wrinkles or breakage of the bag 7 between the retainer 4 and the holder 5 is suppressed, thereby deteriorating the relative positional relationship between the opening 7 c of the bag 7 and the retainer 4 and the gap between them. Generation and expansion can be suppressed.

  Further, in the present embodiment, in a state where the opened bag 7 is accommodated in the holder 5, the retainer 4 is held by the retainer holding portion (holder tab 5g so that the opening 4c of the bag 7 is held in the expanded state by the retainer 4. When held on the upper surface, at least a part of the opening 7c of the bag 7 is nipped between the outer surface of the retainer 4 and the inner surface of the holder 5. Therefore, the deterioration of the relative positional relationship between the opening 7 c of the bag 7 and the retainer 4 and the generation and enlargement of the gap between both can be more effectively suppressed. The restriction and the clamping of the movement of the opening 7c between the outer surface of the retainer 4 and the inner surface of the holder 5 may be performed over the entire circumference of the retainer 4 and the holder 5, or only a part of them. It may be done by

  Further, in the present embodiment, the upper surface opening of the holder 5 is provided with a holder tab 5g extending substantially horizontally and outward, and the tip of the holder tab 5g is accommodated in the container main body 2 When being, it protrudes outward beyond the outer edge of the opening of container body 2. Therefore, when the holder 5 is set in the container body 2, the interference between the fingers holding the holder tab 5g and the opening of the container body 2 is suppressed, so the holder 5 in which the bag 7 is accommodated and the retainer 4 is set. Can be easily set in the container body 2 and removed from the container body 2. However, in the area where the holder tab 5g does not exist, the support rim 2e (see FIGS. 1 and 3) of the container body 2 extends to the same side position as the holder tab 5g and the retainer tab 4b or to the side position outside these. You may

  Further, in the present embodiment, the container 1 further includes an engagement rim 4 f which is a fixing structure for fixing the retainer 4 and the holder 5 to each other. Therefore, the relative positional relationship between the opening 7 c of the bag 7 and the retainer 4 can be suitably maintained, and the suppression of leakage at the time of refilling and after refilling can be further promoted. In addition, the fixing structure for fixing the retainer 4 and the holder 5 to each other is not limited to the aspect in the present embodiment, and various other fixing structures can be adopted. Such other fixing structure may be, for example, of a type in which a projection provided on one of the retainer 4 and the holder 5 is fitted in a hole of a complementary structure provided on the other. As a fixing structure, one using a snap engagement is particularly preferable in that repetition of engagement and disengagement is possible.

  Using the container 1 according to the present embodiment, a package (not shown) is formed by storing the unopened bag 7 that is the bag 7 containing the contents 6 inside the container 1 it can. According to this aspect, the bag 7 and the container in which the contents 6 are contained can be integrally manufactured, distributed, and sold, which is preferable.

  When the retainer 4 is set to the holder 5, a gap may or may not be present between the funnel portion 4 c of the retainer 4 and the cylindrical portion 5 a of the holder 5. When there is no gap, the opening 7c of the bag 7 is held between the funnel portion 4c and the cylindrical portion 5a, and the leakage of the contents 6 from between the retainer 4 and the bag 7 is caused. The relative positional relationship between the retainer 4 and the bag 7 can be suitably maintained by the frictional force related to the holding. In addition, even when there is a slight gap, the movement of the opening 7c of the bag 7 is restricted between the funnel portion 4c and the cylindrical portion 5a, and the generation of the wrinkles and breakage of the bag 7 can be suppressed. The relative positional relationship between the retainer 4 and the bag 7 can be suitably maintained. The smaller the gap, which is advantageous for suppressing the leakage of the contents 6, it is advantageous to design the funnel 4c of the retainer 4 to have a larger horizontal cross section for this purpose. The area around the opening 7c of the case may be buckled, which may increase the possibility that sealing of the gap can not be promoted. Therefore, the size of the gap is preferably determined experimentally according to the mechanical characteristics (especially hardness) of the material of the bag 7 and the like.
